In order to solve the problem that the conventional relay protection tester can not fully test the relay protection device with the operation circuit board,through the research on the operation circuit board of the relay protection device and the existing simulated circuit breaker.A design method for the function board of embedded simulated circuit breaker for automatic debugging of the whole device is proposed.The simulated circuit breaker adopts the integrated circuit design concept with digital circuit as the core.It uses ARM microprocessor as the main controller to communicate with relay protection tester and process real-time signal,so as to realize the tracking and control of relay protection device jump-in.At the same time,the modular hardware design is adopted,and the corresponding test functions are all integrated into one function board,which is seamlessly integrated into the relay protection tester.The long-term application shows that the method realizes the one-button automatic test of the whole logic function of the relay protection device,which effectively improves the debugging efficiency of the relay protection device.
